Whether this is an actual person from today or the future or deep past or came from another planet who traveled back to Charlie Chaplin's times or just someone who is eccentric or someone who has an early large style hearing aid of those times, no one might ever know for sure because we are not there to actually find out which it is. But it sure looks like someone talking on their cell phone or interplanetary communication device. Back then who would know? They just might think she was strange or different but would have no real idea what she was doing because No one had a cell phone or any small personal wireless communication device then. Maybe 100 years from now a photo will show up that we will recognize someone doing something you could then but shouldn't be able to now as well.
